IEC 60947-5-5:2026 provides detailed specifications relating to the electrical and
mechanical construction of emergency stop devices with mechanical latching function and to
their testing.
This document is applicable to electrical control circuit devices and switching elements which
are used to initiate an emergency stop signal. Such devices can be provided with their own
enclosure and will be installed according to the product documentation.
This document does not apply to:
– emergency stop devices for non-electrical control applications, for example hydraulic or
pneumatic;
– emergency stop devices without mechanical latching function.
An emergency stop device conforming to this document can also be used as part of an
emergency switching off means in compliance with IEC 60364-5-53.
NOTE See also IEC 60204-1:2016 and IEC 60204-1:2016/AMD1:2021, 9.2.3.4.
This document does not address specific requirements on acoustic noise as the noise emission
of electrical emergency stop devices with mechanical latching function is not considered to be
a relevant hazard.
